HYDRANT.

Specification forming part of Letters Patent Not 19,206, dated January 26, 1858; Reissued July 18, 1871., N04 4.475.

To all whom t may concern.'

Be it known that We, VVASHBURN RACE and S. R. C. MATHEws, of Seneca Falls, in

the county of Seneca and State of New York,`

have invented a new and Improved Hydrant; and We do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a vertical central section of our improvement. Fig. 2, is a horizontal sect-ion of do., taken in the line Fig. 1. Fig. 3, is akdetached View of the annular valve. Fig. 4, is a detached side View of the device by which the valve rod is operated. Fig. 5, is a detached view of the wrench.

Similar letters of reference indicate corresponding parts in the several figures.

The invention consists, 1st, in a novel construction and arrangement of valves whereby the waste pipe or orifice is opened as the induction pipe is closed and vice-versa, and the perfect operation'of the valves insured, both being operated by a single lever or wrench.

The invention consists, 2d, in a peculiar construction and arrangement of parts as hereinafter shown whereby the hydrant may be readily detached from its base and removed or withdrawn without the trouble and expense of excavating.

To enable those skilled in the art to fully understand and construct our invention we will proceed to describe it.

A, represents the case of the hydrant the upper part of which (a) may be of any appropriate and ornamental form provided with one or more horizontal nozzles B. The lower part (b) of the case is smaller in diameter than the upper part and is of cylindrical form, the part is below the surface of the ground, and the part (a) above it.

The lower part (c) of the part (b) of the case is enlarged somewhat in diameter and an annular valve B, is fitted therein. This valve is formed of a fiat ring grooved circumferentially in its exterior surface to receive a packing (e) which may be of leather or other suitable material. The ring (d) is provided with a cross bar (f) having a hub or boss (e) at its center in which the lower part of a rod C is fitted, said rod having a shoulder (g) formed on it which serves as a bearing for the upper edge of the hub or boss, and a nut (it) is placed on the rod below the hub or boss said nut, fitting on a Ascrew thread by turning the nut in the proper direction the valve B may be firmly secured on the rod. Through the ring (d) of the valve B a screw passes, said screw passing through the ring at a point directly opposite an opening (j) in the part (c) of the case.

The lower end of the part (o) has a screw thread formed on it and is screwed into the upper end of a curved or bent pipe D which is tted permanently in the ground and communicates with the main. The upper end of the pipe D is provided with a flanch (la) and a small spout or nozzle The fianch (7c) extends all around the pipe D and itreceives the lower end of a cylindrical jacket E, which is permenently fitted in the ground. An annular piece of packing is interposed between the upper end of the pipe D and the lower end of the part (c) of the case.

Within the lower part of the part (o) of the case a screw thread is formed to receive an annular valve seat F, said seatl being screwed into the lower end of G represents a valve which is formed of .two parts (n) (o), the part being of cup form and containing a nut (p) by which the valve G is secured to the lower end of the rod C, a, screw thread being on the lower end of the rod. The other part (o) of the valve is a cap which is .screwed down upon a packing (g) which, when said valve is closed bears against the seat F, as plainly shown in Fig. 1. The valve G is allowed to turn freely on the rod C.

Around the outer side of the part (c) of the case A a groove (1") is made, said groove being in the same plane with the opening (j) in the part (c) and the spout or nozzle (l) on the pipe D.

The lower end of the upper part (a) of the case A is provided with a flanch (s) which lits over a flanch (t) on the upper end of the jacket E. In the upper end 0f the part (a) of the case A 'there is screwed a cap H. The cap H is screwed into a recess (u) in which packing (o) is placed the above parts forming a stuffing box.

To the upper end of the rod C, a yoke I is attached and a cam or eccentric J, is fitted within the yoke. The cam J is placed upon a shaft K which has its bearings in a fianch (a) on the upper part (a) of the case A. One end of the shaft K, projects beyond the edge of the flanch and has a square formed on it to receive a wrench L shown in Fig. 5. The sides of the yoke I are slotted vertically as shown at (22'), Fig. 4c, the shaft K passing through said slots. The yoke I is covered by a cap M, the lower edge of which is provided with a flanch (0) which is fitted on the flanch (a) of the case and secured to it by screw bolts.

The ring` (d) of the annular valve B may be provided withv lugs (6) as shown in Fig. 3, said lugs fitting in grooves in the case in order to prevent the valve from turning casually. n

The wrench L has a fork at each end, one fork fitting the square on the shaft K, and the other fork tting the nut The upper end of the cap H also has grooves or recesses made in it to receive one end of the wrench L for the purpose of turning the cap.

The operation is as follows By applying the wrench L to the square on the shaft K the cam o-r eccentric J, may be turned withoutl raising or moving the cap M, and the rod C may be raised and lowered thereby. When the rodl C is raised the valve G bears against its seat F, and the water from the main is prevented from passing into the case A of the hydrant. And when the valve Gr is closed the valve B, is above the opening (j) and therefore the water within the case A may pass out through the opening into groove (r) and out 'at spout or nozzle (l). When the rod C is lowered the valve G opens and the annular valve B passes over the opening (j) closing the same while the water from the main passes up through the seat F, through the case A and out through nozzle B. Thus it will be seen that when the water is admitted into the case the escape passage (j) is closed and when the water is shut off the said passage (j) is opened. In case any of the parts require to be repaired the whole hydrant may be raised, the jacket remaining stationary, by merely unscrewing the lower part of (o) from the ulpper end of the pipe D. This is effected of course by turning the case A. By this means no excavating is necessary in order to repair the hydrant as it may be removed and replaced without difficulty.

IVe do not claim broadly for we are aware that hydrants have been constructed and their parts arranged in various ways so that they could be removed for repairs without excavating, the parts being rendered capable of being withdrawn from the case; but we are not aware that an arrangement like ours has ever been used for effecting the purpose, neither do we claim the casing of hydrants when the case and base or pipe D are in one piece and permanently attached to the pipe from` the main as that has been previously done. Neither do we claim separately the arrangement of the valves B Gr, but

We claim,

l. The annular valve B and the disk valve G attached to the rod C, in combination with the escape or leak opening (j) and seat F, the abo-ve parts being arranged to operate as and for the purpose set forth.

2. The combination of the case A, induction pipe D, provided with flanch (7c), and the jacket E, when arranged as herein shown and described to effect the desired end, towit, the ready removal, when necessary, of the case and working parts of the hydrant for repairs.
